Embodiment Construction

[0052] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0053] refer to figure 2 The basic network structure corresponding to the SRIOV pass-through PCI acceleration hardware management solution based on the perception acceleration capability is shown, and the network structure includes the following units:

[0054] Virtual machine (VM), the application program (APP) running in each VM, in the NFV scenario, the APP corresponds to VNF, the virtual acceleration device (vAcc), the host (Host), and the acceleration device hardware (Accelerator ), wherein, virtual acceleration devices (Virtual Function, VF) 1 to VF8 are virtualized by the Accelerator through the SRIOV technology, and there is a corresponding relationship between VF and vAcc.

[0055] figure 2 The IPSec_3DES_2Gbps marked under vAcc is used to describe the acceleration capability of vAcc. Among them, IPSec indicates the acceleration type, 3DES indicates t...

Abstract

The application relates to the technical field of networks, and particularly relates to an acceleration capability adjustment method and device for adjusting an acceleration capability of a virtual machine, aiming to solve the problem of service interruption caused by allocating or releasing PCI acceleration equipment to the virtual machine. The method includes the following steps: determining a virtual machine to be adjusted and an acceleration capability requirement of the virtual machine to be adjusted, and reconfiguring the acceleration capability of at least one virtual acceleration equipment that has been allocated to the virtual machine to be adjusted according to the virtual machine to be adjusted and the acceleration capability requirement. Therefore, by adopting the method provided by the embodiment of the application, the number of the virtual acceleration equipment cannot be changed, the process of restarting the virtual machine to make the newly allocated acceleration capability or the released acceleration capability take effect is not required, and the service interruption cannot be caused.

Description

technical field [0001] The present application relates to the field of network technologies, and in particular to an acceleration capability adjustment method and device for adjusting the acceleration capability of a virtual machine. Background technique [0002] The purpose of Network Function Virtualization (Network Function Virtualization, NFV) is to realize some network functions in common high-performance servers, switches and storage through virtualization technology. [0003] In the NFV evolution scenario, dedicated hardware-based network devices can be deployed on general-purpose servers using virtualization technology, evolving from the traditional combination of "embedded software + dedicated hardware" to the combination of "software + general-purpose hardware" . Specifically, see figure 1 As shown, in order to achieve generalization of hardware, it is necessary to separate the network function (Network Function, NF) program in the network device based on dedicat...
